Alternative implant materials: We evaluated opportunities for materials in high load orthopaedic applications. We determined the most ideal material formulations for specific orthopaedic applications by combining implant specific computational modeling and physical testing.
Soft-tissue impingement: Larger diameter hip implants have been associated with anterior hip pain; however, the precise mechanism for this clinical concern is unknown. HOL scientists used computational modeling to show that anterior soft-tissue impingement occurring with large diameter femoral heads and dual mobility liners may contribute to anterior hip pain. The findings derived from this model were used to develop novel anatomically contoured implant designs. The new implants that were developes as a result of our computational modeling are currently awaiting regulatory clearance.
Knee implant design: We conducted extensive simulations for various activities of daily living to evaluate the impact of different design concepts on restoring normal knee kinematics and kinetics to design an advanced knee replacement system capable of more closely replicating normal joint motion. The device created as a result of our analyses has been cleared by the FDA.
Constrained hip liners: We developed a validated computational model to simulate lever-out resistance of constrained hip liners. This model helps us rapidly evaluate new concepts and make comparisons with current state-of-the-art components.
